To all whom z' may concern:

Be it known that I, PIERRE PLANTINGA, a citizen of the United States,resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Coke-Ovens, of which thefollowing is a speciiication, vthe principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

My invention relates to coke ovens and particularly to coke ovens havingside walls which diverge from the charging toward the discharging end,certain features thereof, however, being particularly adaptable to andadvantageous in connection with coke ovens in which the side walls ofthe coking chambers diverge and in which such chambers inclinedownwardly from the charging toward the discharging end.

The object of the invention is to provide a coke oven which will beeconomical of construction and etticient in its operation.

The annexed drawings and the following description set forth in detailcertain means embodying my invention, the disclosed means, however,constituting but one of Various mechanical forms in which the principleof the invention may be employed.

In said annexed drawings z- Figure 1 represents a section of a frag-vmentary portion of a coke oven installation embodying my invention,taken upon the planes indicated by lines I-I in Fig. 5, the greaterportion of such planes being parallel with the tioor of the retort.

Fig. 2 represents a fragmentary transverse vertical section taken uponthe plane indicated by the line II-II in Fig. 1 and viewed in thedirection indicated by the arrows.

Fig. 3 represents a fragmentary longitudinal vertical section taken uponthe plane indicated by the line Ill-1H in Fig. 1 and viewed in thedirection indicated by the arrows.

Fig. et represents a transverse vertical section taken upon the planeindicated by the line V--IV in Fig. l and viewed in the directionindicated by the arrows.

Fig. 5 represents a transverse vertical section taken upon the planeindicated by the line V-V in Fig. 1 and viewed in the directionindicated by the arrows.

Fig. 6 represents a longitudinal vertical Section taken upon the planeindicated by the line VI-Vll in Figs. l and 5 and viewed in thedirection indicated by the arrows.

Fig. 7 represents a longitudinal vertical section taken upon the planeindicated by the line VII-Vil in Fig. 2 and viewed in the directionindicated by the arrows.

The illustrated embodiment of my invention comprises an outer casing orhousing 1 of the required dimensions, such dimensions depending upon thenumber and size of the @cking-chambers, as will be readily understood.Formed within the casing is a plurality of coking-chambers 2 whosesides, top and bottom are formed of suitable tile la abutting and joinedwit-h each other, the joints formed by the tile elements ruiming in thegeneral direction, that is parallel with the direction, of inclinationof the chambers, and at right angles thereto, as shown in Figs. 4 andThe upper end of each such coking-chamber is closed by means of asuitable removable closure 3 and communieating with such upper or rearend is a charging duct 4 closed by a suitable closure 5, as shown inFig. 4;. Each coking-chamber is furthermore provided with a vertical gastake-oil flue 6 connected with a suitable pipe 7 for conducting thegases formed to the desired point.

The lower or front. end of each chamber is closed by means of a suitableremovable closure 8, as shown in Figs. 1 and el.

The coal is charged through the charging duct 4. into the chamber andwhen the' coking operation is complcteil, the closures 3 and 8 areremoved and the contents removed by pushing same from the rear outthrough the front end, as will he readily understood.

Adjacent. to each side ofeach cokingchamber is a set of parallelcombustionchambers 9, these chambers also zinclining and having adirection of inclination parallel with that of the general direction ofinclination of the cokinchambers as shown in Fig. 5. The upper or rearends of each of the combustion-chambers comprising a given set,communicate with a vertical iiue 10 which in turn communicates with ahorizontal flue 11 which leads to the stack (not shown). This fluereceives and takes off the gases of combustion formed in thecombustion-chamber. Opposite the upper end of each con'dmstion'chaiaber9 a shelf l2 and side ledges 13, this shelf and ledges supporting avalve 14 which may be reached through an opening 15 normally closed bymeans of a removable closure 16, F ig. 5. The efflux of the gases ofcombustion through the lues 10 and 11 are capable of regulation by meansof these valves, as will be readily understood.`

A. longitudinal air duct 17, Figs. 2, l and 5, is provided andcommunicates by means of horizontal passages 18 with a vertical duct 19.The air duct 17 is usually connected with a recuperator (not shown) suchas is ordinarily provided in this class of devices, as will be readilyunderstood. One such duct 19 is located between the front ends of eachtwo adjacent sets of combustion-chambers, as shown in Fig. 1, andcommunicates with a plurality of air inlets 20, one of which is locatedadjacent to the lower end of each combustion-chamber, as shown in Fig.5. These air ducts are controlled by valves 21, Fig. 2, which arelocated in passages 22 normally closed by closures 23 and through whichthey may be reached for adv justment. The influx of air at these pointsis hence capable of regulation. An additional air inlet 24 isprovided,as shown in Figs. 2 and 5, and also controlled by means of a valve 25located in a passage 26 and closed by a closure 27. This last-named airinlet communicates directlyT with the horizontal passage 18, as shown.

Opposite the lower ends of each set oi combustion-chambers is a verticalflue 28 whose lower end communicates with a gas duct 29 which itself isconnected with a suit-- able source of fuel gas (not shown).

rlhe device as above-described operates as follows:

The gas from the duct 29 flows upwardly into the duct 28 and becomesmixed with air from the inlet 24. Additional air from the inlets 20 ismixed with the mixture of air and gas first formed, and is then burned.These gases of combustion pass up through the combustion-chambers 9 andllow out through the lues 10 and 11. During such passage they heat thesides of the cokingchambers and effect the coking operation.

By arranging the apparatus, however, as described, that is, bypermitting the initial combustion to take place at the lower or widerend of the coking-chamber, the maximum temperature will be applied atthis Wider end where it is required, a larger mass of coke being locatedat this point and hence a higher ,degree of temperaturebeing required.As the gases of combustion travel through the chambers or heating flues9, and part with their heat, they are required, as they progress, toheat a volume of coal which grows smaller in the direction of travel ofsuch gases, so that the mass of coal decreases as the gases becomecooler. By suitable regulation ot the valves resaca? thecombustion-chambers lie in planes which intersect one another, thearrangement therefore being such that the adjacent joints break witheach other. By means of this arrangement the cracking of these adjacentwalls is minimized, as will be understood.

The side walls of all the coking-chambers diverge in the same direction,as will be seen in Fig. 1. Fart of the partition walls 30, as is shownin said figure, are rectangular in horizontal section, but certain 'ofthese walls, as for instance wall 31, are built so that their sides willdiverge in the direction opposite from that of the direction ofdivergence of the coking-chambers, as shown.. By providing such awedge-shaped partition wall at suitable intervals, the rectilinear formof the entire installation may be preserved.

In the above-described manner, therefore, l obtain a coke oveninstallation which may contain any required number of cokingchambers,provide means whereby these coking-chambers and hence their contents areuniformly heated, and reduce cracking of the adjacent walls whichexpansion and contraction tends to produce, to a minimum. l am also, bymeans of the above-described 105 construction, enabled to incorporate inthe installation, the diverging or wedge-shaped form of coking chamber,but still preserve the general rectilinear form of the entireinstallation.

Having fully described my invention, what l claim and desire to secureby Letters Patenty is 1. lin a coke oven,l the combination of aninclined coking chamber; a set of parallel 115 combustion chambersarranged one above the other and adjacent to one side of said cokingchamber; avertical duct adjacent to the lower ends of the combustionchambers of said set; a gas suppl for supply- 120 ing fuel gas to saidduct; a p urality of air 1n e ts, one such inlet being locatd adjacentcombustion chambers and adapted to control ihe exit of gases throughsaid upper vertical uct.
